Inventor: FUJITA NOBUO
IPC: B29C65/48
Filed: 1988-12-27
Abstract: PURPOSE:To mold simultaneously with pipe manufacture a joint, prevented from forming a protrusion in the periphery of a connection part even after connection, by constituting the joint connecting the fellow end parts of a resin pipe, forming one end part periphery of the joint in a tapered surface and the other end part internal periphery in a tapered surface of equal slope and fitting both these tapered surfaces to each other to be adhesively mounted. CONSTITUTION:Two resin pipes 1 and 2, manufactured by the winding method, are provided respectively with an insertion port 3 having a tapered surface formed in the periphery in one end part and a receiving port 4 having a tapered surface formed in the internal periphery in the other end part. The tapered surfaces of the insertion port 3 and the receiving port 4 are formed so as to be fitted to each other. Both the resin pipes 1, 2, setting the fellow end parts with their axial center agreeing, are connected by adhesively mounting the insertion port 3 of the resin pipe 1 into the receiving port 4 of the resin pipe 2 by an adhesive agent interposing an annular seal member 7. Accordingly, no surplus protrusion is formed in the periphery of a connection part after connection. These resin pipes 1, 2, in manufacture time, form by roll molding the receiving port and the insertion port in every fixed length of a resin member wound on a core mold 11.

Title: Discharge lamp lighting device
Inventor: SUZUKI HIROSHI
IPC: H05B41/24
Filed: 1997-12-03
Abstract: PROBLEM TO BE SOLVED: To provide a discharge lamp lighting device, capable of starting and lighting on plural discharge lamps in good balance. SOLUTION: In an inverter circuit 13 a high frequency is generated, and a high voltage is induced by the resonation of a ballast choke L1 and a resonating capacitor C1. Voltages to discharge lamps F11, F12 are balanced by a balancer transformer L2 for starting and lighting on. Since unbalance preventing capacitors C4, C6 having capacities of several to about 10 times the capacitance of a floating capacitance are connected to the discharge lamps F11, F12, a starting secondary voltage is not brought into unbalance, even if the floating capacitance parasitizes on a feeding wiring 4. The differing of the starting times of the discharge lamps F11, F12, or the discharge lamps F11, F12 not lighting on is prevented so that a starting characteristic is enhanced.  The application of a voltage higher than necessary resulting from the unbalance is avoided, the prolonging of life for the discharge lamps F11, F12 is contrived.

Title: Mask pattern designing method and mask
Inventor: IMAI AKIRA
IPC: G03F1/80
Filed: 1992-12-15
Abstract: PURPOSE:To improve the accuracy of a desired pattern edge position and to suppress the fluctuation in the size of the transfer pattern with a fluctuation in phase shifter film thickness by correcting a light shielding part in such a manner that the edge region where the intensity of exposing light is weakened is included in the light shielding part side. CONSTITUTION:A light shielding film 21 of a chromium film, etc., formed on a mask substrate 20 is worked to form the light shielding pattern; thereafter, the phase shifter film (transparent film) 22 is laminated thereon. The film is formed to form the phase shifter pattern. The effectively diminished transmission pattern size is corrected and increased if the transmission pattern edge is previously moved by as much as the size of the transferred resist pattern fluctuates. As a result, the light intensity distribution similar to the light intensity distribution on the substrate for the transmission pattern edge where the phase shift film is not formed is obtd. Then, the fluctuation in the transfer pattern size is suppressed. The fluctuation in the transfer pattern size is suppressed even if the focus is deviated by executing the size correction in such a manner.

Abstract: PURPOSE:To make it possible to count the number of etch pits with good accuracy by a method wherein a picture signal obtained by a microscopic camera is turned into a binary signal, the area of an etch pit and the roughness of the contour of the etch pit are extracted from image data on the binary signal as the amount of features in every etch pit or in every block of etch pits and this amount of features is compared with a reference value to calculate the number of etch pits. CONSTITUTION:A picture signal obtained by a microscopic camera (CCD camera) 1 is turned into a binary signal by an image processing device 2, at least the area of an etch pit and the roughness of the contour of the etch pit are extracted from image data on the finary signal as the amount of features in every etch pit or in every block of etch pits and this amount of features is compared with a reference value to count the number of etch pits. Moreover, as the extracted amount of features and the reference value, which is compared with the amount of features, are contrived so as to be decided on the basis of a measured value to be obtained from the image data that becomes an object of inspection, an error due to a variability in etching conditions, such as the material of a crystal, an etching liquid, an etching time, the orientation of a face and the like, can be corrected.

Title: Method for conditioning dredged earth and sand
Inventor: HANADAKE ICHIROU
IPC: C09K17/02
Filed: 1995-12-22
Abstract: PROBLEM TO BE SOLVED: To provide a method for conditioning dredged earth and sand by which the elution of ammonia contained in underwater earth and sand can he effectively inhibited by adding cement to the earth and sand, kneading them, adding zeolite to the mixture and kneading the resulting mixture again to produce an easily utilizable cemented product. SOLUTION: Dredged earth and sand are conditioned by adding cement to underwater earth and sand, kneading them, adding zeolite to the kneaded mixture and kneading the resultant mixture again. According to this process, the elution of ammonium can be effectively inhibited when underwater earth and sand is solidified with cement, and the solidified earth and sand are returned to the bottom of water or when it is used for water surface refilling. Because the zeolite is a substance being a silicate of Al and Na and can selectively and tightly adsorb ammonium, the elution of ammonia from underwater soil and sand can be effectively inhibited.
